Several changes.
When using sbatch to launch through the queue system, the stdout can be
written to the name in CHPL_LAUNCHER_SLURM_OUTPUT_FILENAME plus jobid
and .out, so its easy to tell a stdout filename. By default it continues
to write it to the name of the chapel program plus jobid.out

Now it deletes all the temporal files, unless DEBUG_LAUNCH is defined.
I have tried to simplify the background launch in the interactive mode,
but for a background launch the sbatch mode (defining
CHPL_LAUNCHER_USE_SBATCH) must be used.
